Testing time 120 seconds, +/-3 seconds Water flow rate 610 litres/hour minimum Note: The water pressure and water temperature settings must be measured immediately behind the nozzle. Conditioning and Test Conditions All
8、 test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure 1. The equipment is filled with water without an
9、y additional cleaning agents and heated. 2. Before testing, the equipment must be adjusted to the required test pressure for the specified distance. 3 Scribe the panel with an X scribe, over the whole area to be exposed to the water jet. 4. The gun with the nozzle is fixed to the required distance f
10、rom the nozzle to the painted surface which is to be tested. The jet of water has to be directed vertically onto the painted surface. 5. Spray water for the specified length of time. 6. The surface is dried and evaluated after cooling to 23 +/- 2 C. 7. Report any failure (e.g., loss of gloss, loss of adhesion, surface deterioration). The principal failure mode is paint peeling. Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
